Torch  Also, for night sky photography, you need to be in a place where the environment is mostly dark, you should avoid a place with the light source and the urban pollution, so in this sense I would like to tell you that I have tried out the night sky to shoot my city Kolkata, but since the sky in the city t is dirty and it is not too dark, I could not capture the night sky from here. Rather, you can try from a place that is far away from the city. One of the reasons why I like to visit mountains is night-time sky photography. In the mountains, the air is pollution-free and there is no or minimal light source at night, so it is very easy to detect the night sky. So try capturing those glittering stars on your next mountain trip.
What settings do you need to be aware of before night-sky photography in your camera?
Well, I do not take a deep logic behind every attitude. If you have any question about the logic behind each setting, you can leave a comment below, and I'll certainly answer that.
Now here it is –
Remove any type of filter, polarizer from your lens.
Set your camera in manual mode.
Turn on the camera in manual focus
Disable noise reduction for high ISO sensitivity
Disable long term stress reduction
Always photograph the night sky Photo with RAW image format
Set for your Set the ISO value to between 1600 and 6400
Set your camera aperture to f 3.5
Set the camera shutter speed or exposure time to between 20 seconds and 30 seconds
Note: You can lower your f-number to 1.4 or 2.8 if your camera allows it.
Example of night sky star camera settings in Nikon D5300 with 18 mm lens
Now here's a hook to s joke a decent night sky photo your camera needs correct exposure settings. As with the shutter speed, you need to set between 6 and 45 seconds to allow enough light in your shots. But if you leave it open too long, your camera will detect the movement of the stars and the photo will blur when you zoom.
There is a rule for this, that is
"500 Rule" . To know what the perfect exposure will be, you must follow "500 Rule" .
Here is the 500 rule of photography:
500 divided by the focal length of your lens = The longest exposure (in seconds)
For example; When taking a picture with an 18mm lens on a full frame camera.
500/24 = 21 seconds which you can round to 20 seconds. This formula applies to all full-frame cameras.
If you are using the crop sensor camera now, multiply the crop factor by the focal length before dividing that number by 500.
Sony & Nikon = 1.5 Crop Factor
Canon = 1.6 Crop Factor
So for example: My DSLR is Nikon D5300 crop sensor camera , So I follow this rule
My lens focal length
18 mm .
Shutter Speed = 500/18 mm x 1.5 = 18.51 sec. ~ 20 sec.
Now you can take pictures in different settings as below to give a try and error and see which is the best capture. I recorded earlier with the following settings. You can also find some of my shots with the following camera settings:
ISO: 1600 F: 3.5 SHUTTER: 20 seconds
ISO: 1600 3.5 SHUTTER: 25 sec.
ISO: 1600 F: 3.8 SHUTTER: 30 sec.  ISO: 2400 F: 3,5 SHUTTER: 20 seconds
ISO: 3200 F: 3.8 SHUTTER: 25 seconds
ISO: 3200 F: 3.5 SHUTTER: 30 seconds
This way you can use the combination change from ISO and shutter speed and try to get your desired shot.
Then you need to mount your camera on tripod. Make sure your tripod does not wobble during recording.
Now you come to the most important part of it. How to focus manually in the dark state. For this you have to illuminate an object near your camera. You can use your flashlight or headlamp to adjust the focus wheel of your lens and check your camera's display when it's focused. Now set the camera timer for 5 seconds or 10 seconds and press the shutter button (you can also use the wireless remote control). After a while, check this out, if you are satisfied with the frame, come to exposure and focus well or try again. Remember to take 5 – 6 shots so you can choose the change to choose the perfect one.

I hope you get an idea how to take photos of night scenes. In my next tutorial, I'll explain how to edit the night sky image in post-processing software like Lightroom or Adobe Photoshop. I use Adobe Lightroom for post-processing my night sky, Milky Way photos.
